Servo Tester

Hi! I'm Sevde. I'm living and studying in Turkiye. My financial situation is not good. so i can't print it.Using the NE555 timer IC, an astable multivibrator circuit is created. The 555 timer is a three-terminal IC: ground (GND), supply voltage (VCC), and output (OUT). The output pin generates a series of square wave pulses where the pulse width and frequency are determined by external components.

In this circuit, the 555 timer is configured in astable mode. This means the output continuously switches between high and low voltage levels. The pulse width is determined by R1 and C1, while the frequency is determined by R2.

When the circuit starts operating, the C1 capacitor begins to charge through the R1 resistor. When the voltage across C1 reaches 1/3 VCC, the threshold value of the 555 timer is triggered, and the output drops to a low voltage level. C1 then begins to discharge through the R2 resistor. When the voltage across C1 reaches 2/3 VCC, the trigger pin of the 555 timer is triggered, and the output rises to a high voltage level. This process repeats, generating a series of square wave pulses at the output.

The pulse width is determined by the values of R1 and C1. The higher the value of R1 and the larger the value of C1, the longer the pulse width. The frequency is determined by the value of R2. The higher the value of R2, the lower the frequency.

An LED is controlled by the state of the output. When the output is at a high voltage level, the LED lights up, and when the output is at a low voltage level, the LED turns off.
